<p>PROBLEM TO BE SOLVED: To make a retainer stably rotate, and suppress the generation of vibration of the retainer, in a conical roller bearing.SOLUTION: An inner ring 11 has a large flange part 23 having an inner side face 24 which contacts with a large end face 31 of a conical roller 13. A retainer 14 has: a pocket side face 17a as a first positioning part which limits the movement of the retainer 14 to one side in an axial direction by contacting with the large end face 31 of the conical roller 13; and a protruded piece 19 as a second positioning part which limits the movement of the retainer to the another side in the axial direction by contacting with the inner side face 24 of the large flange part 23.</p> |
